In the past month, there have a been a few times when I press "Play" and the tonearm begins to move out over the record, but then stops. It doesn't set down or go back, it just stops. I have to press "Stop" and then press "Play" again to get it to move over the record and set down. In addition, for the first time the other night, I was two thirds of the way through a record, when the tonearm suddenly lifted up and hung there. I had to press "Stop" to get it back to the rest before then using the << to reposition it over the song. Thoughts?

If not already thoroughly serviced, it will need it by now.
After 30 years they all do.

I cannot point my finger to a particular point or component in your deck and as soon as you start fiddling about
inside the Beogram more faults will develop due to vibrations etc. It's all very normal.

Fault symptoms vary immensely but new capacitors, fresh solder joints, a good cleaning,
fresh lubricants and adjusting according to factory specs will usually work wonders.

Not a deck for the beginner servicing things on the kitchen table (with all respect), it can be a bit complicated and stubborn
but fortunately these decks are easily worth the trip to an experienced repairer.

Hi Martin,

Thanks for the reply, I'm always eager to hear your thoughts.

I sent the board to you for new capacitors and fresh soldering about a year ago, but I've never done any cleaning and lubrication or other adjustments. I guess if the symptoms recur (they haven't in a week or so), I'll either attempt to service it myself or just bring it someone I know who's a former B&O turntable tech.

Best,

Matt

Hi Matt,

Sorry I didn't recognize you. Laughing

Clean and re-lubricate the threaded shaft and the carriage bushing and also the shaft opto.
Check the adjustments of the front panel << and >> buttons.

No problem. There are so many Beogram owners to keep track of. Wink

I should be able to handle the cleaning and re-lubing, as well as the adjustments of the front panel buttons. But If I have questions, I'll be back!

Hi Martin,

Circling back to this at last, I have some questions:

1. How do I access the section of the threaded shaft that the carriage assembly is covering? Do I need to plug in the table with it in the service position and use the << and >> buttons to move the assembly?

2. Which part #s in the service manual are the carriage bushing and the shaft opto? Or do you have some other visual reference?

3. What lubricants do you recommend for the above?


Thanks

Matt

So I figured this out. Sorta. Big Smile

1. There may have been a different/better way, but I simply opened up the unit, cleaned and oiled the exposed part of the threaded shaft, used the << button to move the tonearm assembly over the area I just finished, and then cleaned and oiled the rest.

2. I couldn't determine where the carriage bushing was located. I did clean the two ends of the threaded shaft and lubed with white lithium grease (that's what was already on it).

3. In addition to the white lithium grease used for the ends of the threaded shaft, I oiled the shaft itself with some light fishing reel oil that I've used for similar turntable applications.

Now for the post script: I reassembled everything and found that the problem was fixed! Great. Just one thing: I now had no sound out of the left channel. After reading some other posts on here, I had a feeling that I had broken a solder connection to the output plug. Sure enough, that's exactly what it was. I re-soldered the connection, and now I'm back in business.

Given how much I've benefited from this forum, both in the past and just recently, I think it's time to become a paying member.
